Rolls-Royce Cullinan electric aims to beat Bentley’s future SUV

The world of ultra-luxury cars is entering a decisive phase. Now, with electric power, Rolls-Royce is preparing the future of its SUVs. The next move could be to leapfrog Bentley without losing its sense of absolute comfort.

The race for the ultra-luxury electric SUV

Indeed, the project for a battery-powered Cullinan is gaining in credibility. What’s more, the model ‘s recent update marks a useful technical step towards a complete transformation. As a result, the brand is aiming for a 100% electric range by 2030, a public target already announced.

Rolls-Royce – Cullinan (SUV; electric version): the battery-powered version is emerging as the future pillar of the segment. The study targets an identical size, a benchmark range and quiet operation.

Bentley is also preparing a large zero-emission SUV, due to be launched around 2026. The window of opportunity is therefore before this key date for capturing demand. On the other hand, the industrial agenda and global homologation will have to be kept to.

“The very high-end doesn’t look for one-upmanship, it orchestrates calm time and consistency.”

Timetable, platform and rivalries

Bentley – Bentayga (SUV; plug-in hybrid): the PHEV serves as a credible bridge to the full switchover. As such, it offers smooth, everyday city driving, with several dozen kilometers in electric mode.

Mercedes-Maybach – EQS SUV (SUV): this electric vehicle confirms the company’s appetite for large, refined vehicles. What’s more, the approach emphasizes smoothness and connected services, in phase with chauffeur-driven use.

• Declared goal: 100% electric range by 2030 for the Goodwood-based automaker
• Cullinan “Series II” modernized in 2024, a useful base before electrification
• Bentley’s first electric model expected around 2026
• Spectre already on the market, technical benchmark for the next wave
• Cullinan Black Badge: 6.75-litre twin-turbo V12, 600 bhp, from €391,800

Technology, comfort and energy constraints

Rolls-Royce – Spectre (coupé; Black Badge): this electric coupé sets the house standard for immediate torque and quietness. A Black Badge is also in the offing, to take dynamic character and stylistic expression a step further.

The aluminum “Architecture of Luxury” accepts motors, batteries and high-capacity electronics. However, the weight of the vehicle means that a great deal of work has to be done on mounts, tires and suspension acoustics. Consequently, the calibration of the powertrain must guarantee smooth thrust, without jerking or parasitic noise.

BMW – iX3 (SUV): this more compact model illustrates the pragmatic electrification of premium SUVs. In short, it reminds us that efficiency and thermal management are as important as raw power.

The 350 kW network is now making headway in Europe and the USA. However, power stability still depends on the load curve and temperatures. In short, planning remains an essential part of a smooth long-distance journey.

Customers, uses and services

Bentley – Flying Spur (sedan): the hybrid version targets discreet daily commutes without sacrificing presence. Secondly, the sedan reassures customers who don’t want to go all-electric too quickly.

Ultra-demanding customers also expect well-oiled initial services and turnkey solutions. However, adoption requires a guarantee of smoothness, including when recharging at home. That’s why Rolls-Royce is working on the overall experience, from door-to-door contact to advanced journey planning.

Range, image and perspective

Rolls-Royce – Cullinan Black Badge (SUV; V12 675 Bi-Turbo 600hp; €391,800): this combustion-powered flagship is reminiscent of the level of performance expected tomorrow in electric form. As a result, its specification sheet is striking, with a V12 6.75
